The Great Global Warming Swindle is a polemical documentary film that suggests that the scientific opinion on climate change is influenced by funding and political factors, and questions whether scientific consensus on anthropogenic global warming exists. The program was formally criticised by Ofcom, the UK broadcasting regulatory agency, which upheld complaints of misrepresentation made by David King. The film, made by British television producer Martin Durkin, presents scientists, economists, politicians, writers, and others who dispute the scientific consensus regarding anthropogenic global warming. The programme's publicity materials assert that man-made global warming is "a lie" and "the biggest scam of modern times." Its original working title was "Apocalypse my arse", but the title The Great Global Warming Swindle was later adopted as an allusion to the 1980 mockumentary The Great Rock 'n' Roll Swindle about British punk band the Sex Pistols. The UK's Channel 4 premiered the documentary on 8 March 2007. The channel described the film as "a polemic that drew together the well-documented views of a number of respected scientists to reach the same conclusions. This is a controversial film but we feel that it is important that all sides of the debate are aired." According to Hamish Mykura, Channel 4's head of documentaries, the film was commissioned "to present the viewpoint of the small minority of scientists who do not believe global warming is caused by anthropogenic production of carbon dioxide."

MegaStructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia. Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products. Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases this involved the development of new materials or products that are now in general use within the construction industry. MegaStructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first. This type of project is known as a Megaproject.
